I’m not sure I understand how quoting Gen Con’s policy statement in an event description is in conflict with Gen Con standing by that policy statement.
Some people want to "request" masks, which is different from "recommend" masks. It is a way to exert social pressure on people to wear masks above and beyond the recommendation. Basically, they are signaling that you are not welcome at their table unless you are wearing one.
And, to me, that's just fine. The social pressure works both ways, if no one signs up for your event because of your request, then you might want to re-think it for 2024.
And, without snark, the White House just said they're planning on ending the emergency on May 11th.
